DETAILED DESCRIPTION

According to aspects of the disclosure, a file management technique is provided for use in mobile terminals and other electronic devices. According to one aspect of the disclosure, a copy of an original file is uploaded by a mobile terminal to a remote storage device. After the original file is uploaded to the remote storage device, an optimized file corresponding to the original file is generated. The optimized file may be a version of the original file that is different from the original file in at least one aspect. For example, the optimized file may be smaller in size than the original file or the optimized file may have at least one of its attributes (e.g., read/write attributes) set differently from the original file. After the optimized file is generated, the original file can be deleted from the memory of the mobile terminal and only the optimized file can be retained in the memory of the mobile terminal.

According to aspects of the disclosure, the optimized file may be generated by either one of the mobile terminal and the remote storage device. In some implementations, the optimized file may be provided to the mobile terminal by the storage device upon the storage device receiving a copy of the original file. Thus, when a backup copy of the original file is stored at the storage device, the storage device may respond by returning an optimized version of the original file to mobile terminal.

According to aspects of the disclosure, the optimized file may be generated based on environment information of the mobile terminal. The environment information may identify processing power, memory space available, and or any other suitable characteristic of the hardware and/or software environment of the mobile terminal. Thus, if the mobile terminal has a low-resolution display and the original file is an image, the optimized file may be generated in such a way so that its resolution does not exceed the native resolution of the mobile terminal's display.

According to aspects of the disclosure, the optimized file may be associated with link information for retrieving the original file from the storage device. The link information may include any suitable identifier for retrieving the original file from the remote storage device, such as a Uniform Resource Locator, mapping number, etc. In some instances, the link information may be encoded directly into the optimized file.

According to aspects of the disclosure, the optimized file may be provided back to the mobile terminal when the optimized file is displayed and a predetermined input to the optimized file is sensed. For example, if the optimized file is read-only and the original file is editable, when a user attempts to edit the optimized file, the original file may be automatically retrieved from the storage device by the mobile terminal and displayed in place of the optimized file. In some implementations, the original file may be retrieved from the storage device based on information that is embedded into the optimized file.

FIG. 2B is a block diagram illustrating an example of a configuration of the processor 122 according to aspects of the disclosure. As illustrated, the processor 122 may include a backup state detection unit 210, a file conversion controller 220, a file storage controller 230, and a file transmission controller 240. Each of the backup state detection unit 210, the file conversion controller 220, the file storage controller 230, and the file transmission controller 240 may be implemented in software (e.g., via one or more processor instructions), in hardware (e.g., via one or more dedicated or shared electronic circuits), and/or as a combination of hardware and software. Although the backup state detection unit 210, the file conversion controller 220, the file storage controller 230, and the file transmission controller 240 are depicted as discrete modules, in some implementations two or more of them may be integrated together.

The file transmission controller 240 may transmit an original file stored at the memory 110 of the electronic device 100 to the storage device 10. For example, when the electronic device 100 is connected to the storage device 10 by wire or wireless, the file transmission controller 240 may control to transmit an original file to the storage device 10.

The backup state detection unit 210 may determine whether backup of the original file transmitted from the electronic device 100 to the storage device 10 is complete. For example, when backup of an original file to the storage device 10 is complete, the backup state detection unit 210 may receive a backup completion signal corresponding to the original file from the storage device 10. Additionally or alternatively, when backup of an original file at the storage device 10 is complete, the backup state detection unit 210 may transmit a backup completion signal corresponding to the original file to the storage device 10 or may provide a backup completion signal to the file conversion controller 220.

The backup state detection unit 210 may provide the backup completion signal received from the storage device 10 to the file conversion controller 220.

The file conversion controller 220 may execute the file conversion module 117 stored at the memory 110 and optimize an original file to produce an optimized file. For example, when backup of an original file to the storage device 10 is complete, the file conversion controller 220 may compress the original file to produce an optimized file. The original file may include an image file, a video file, a text file, a sound file, and/or any other suitable type of file.

FIGS. 9A-B are diagrams illustrating an example of a technique for optimizing an original file to produce an optimized file. As shown in FIGS. 9A and 9B, the electronic device 100 may convert an original image 900 having a resolution of 2048*1536 to an optimized image 910 having a resolution of 640*480. In some implementations, after a copy of the original image 900 is stored on the storage device 10, the electronic device 100 may delete the original image 900 from the memory of the electronic device 100 and store the optimized image 910 in its place. By doing so, the electronic device 100 may reduce the memory space needed to store the image. In some implementations, the resolution of the optimized image 910 may be set by the user.

FIGS. 10A-B are diagrams illustrating an example of a technique for optimizing an original file to produce an optimized file. As shown in FIGS. 10A and 10B, the electronic device 100 may compress an original image file 1000 that is stored in a Bitmap (BMP) format to produce an optimized image file 1010 that is stored in the Joint Photographic coding Experts Group (JPEG) format. Because the JPEG format has a high compression ratio in comparison to the Bitmap format, the optimized image file 1010 may occupy less memory space than the original image file 1000. Additionally or alternatively, in some implementations, the electronic device 100 may increase the compression ratio of the original image file 1000 without changing the file's format. It is to be understood that any suitable compression technique may be used to compress the original image file 1000.

FIGS. 11A-B are diagrams illustrating an example of a technique for optimizing an original file to produce an optimized file. As shown in FIGS. 11A and 11B, the electronic device 100 may convert an original video file 1100 having a resolution of 1280*720 to an optimized video file 1110 having a resolution of 400*240 and store the optimized video file 1110 as a replacement to the original file. In some implementations, the resolution to which the original video file 1100 is converted may be set by the user.

FIGS. 12A-B are diagrams illustrating an example of a technique for optimizing an original file to produce an optimized file. As shown in FIGS. 12A and 12B, the electronic device 100 may compress an original video file 1200 that is encoded in the Audio Video Interleaved (AVI) format to produce an optimized video file 1210 that is encoded in the Quick Time Movie (MOV) format. By doing so, the electronic device 100 may reduce the size of the original video file 1200. Although in this example the electronic device 100 increases the compression ratio of the original video file 1200 by changing the original file's encoding scheme, in other examples, the electronic device 100 may only change the compression ratio without changing the encoding scheme. Any suitable technique for encoding and/or compressing the original video file 1200 may be used.

FIG. 13 is a diagram illustrating an example of a technique for optimizing an original file to produce an optimized file. As shown in FIG. 13, the electronic device 100 may convert an original text file 1300 encoded in the Document (DOC) file format to an optimized text file 1310 that is encoded in the Portable Document Format (PDF) file format. In some implementations, the optimized text file 1310 may have the same format as the original text file 1300. In such instances, the optimized text file 1310 may be a compressed version of the original text file 1300. Additionally or alternatively, in some implementations, optimizing the original text file 1300 to produce the optimized text file 1310 may include changing one or more attributes of the original text file. For example, the original text file 1300 may be editable while the optimized text file 1310 may be read-only.

FIG. 3 is a flowchart of an example of a process, according to aspects of the disclosure. According to the process, at operation 300, the electronic device 100 connects to the storage device 10.

At operation 310, the electronic device 100 transmits a copy of an original file stored at the electronic device 100 to the storage device 10.

At operation 320, the electronic device 100 determines whether the transmission of the original file is complete. In some implementations, the determination may be performed by using the backup state detection unit 210. If the transmission is complete, the backup state detection unit 210 may receive a backup completion signal from the storage device 10 indicating that the transmission has been completed. Additionally or alternatively, when the transmission of the original file is completed, the backup state detection unit 210 may transmit a backup completion signal to the storage device 10. Additionally or alternatively, when the transmission of the original file is completed, the backup state detection unit 210 may provide a backup completion signal to the file conversion controller 220.

At operation 330, the electronic device 100 generates an optimized file based on the original file. The electronic device 100 processes the original file to produce an optimized file. As discussed above, optimizing the original file may include one or more of:

-   -   (1) Changing the encoding scheme used to encode the content of         the original file;     -   (2) Compressing the original file;     -   (3) Changing one or more attributes of the original file that         specify whether the file can be edited.     -   (4) Changing a format of the original file; and     -   (5) Changing a resolution of media content that is stored in the         original file.

In some implementations, operation 330 may be performed by the file conversion controller 220 of the electronic device 100. Although in this example the optimized file is generated by the electronic device 100, in other examples the optimized file may be received by the electronic device 100 from the storage device 10 after operation 320 is completed. Additionally or alternatively, in some implementations, the optimized file may be generated by the electronic device 100 based on environment information of the electronic device 100.

FIG. 4 is a flowchart of an example of a process, according to aspects of the disclosure. According to the process, at operation 400, the electronic device 100 connects to the storage device 10. At operation 410, the electronic device 100 transmits original file to the storage device 10.

At operation 420, the electronic device 100 determines whether the transmission of the original file is complete. In some implementations, operation 420 may be performed in the same way as operation 320.

At operation 430, the electronic device 100 generates an optimized file based on the original file. The electronic device 100 obtains an optimized file corresponding to the original file. The optimized file may be an optimized version of the original file. As noted above, the optimized file may be generated by one or more of:

-   -   (1) Changing the encoding scheme used to encode the content of         the original file;     -   (2) Compressing the original file;     -   (3) Changing one or more attributes of the original file that         specify whether the file can be edited.     -   (4) Changing a format of the original file; and     -   (5) Changing a resolution of media content that is stored in the         original file.

In some instances, the optimized file may be generated by the electronic device 100. For example, by executing the file conversion module 117 stored at the memory 110, the file conversion controller 220 of the electronic device 100 may generate an optimized version of the original file.

At operation 440, the electronic device 100 replaces the original file with the optimized file. In some implementations, replacing the original file with the optimized file may include deleting the original file from the memory (e.g., volatile and/or non-volatile memory) of the electronic device 100 and retaining only the optimized file in the memory of the electronic device 100.

Additionally or alternatively, in some implementations, replacing the original file with the optimized file may include associating the optimized file with link information for retrieving the original file from the storage device 10. The link information may include an Uniform Resource Identifier (URL) for retrieving the original file, a mapping number corresponding to the original file, a thumbnail corresponding to the original file, and/or any suitable identifier that can be used to retrieve the original file from the storage device 10.

In some implementations, the link information may be generated by the storage device 10. For example, in some instances, the storage device 10 may store a mapping table that relates mapping numbers with corresponding file paths. In such instances, the mapping number for the original file may be provided to the electronic device 100 by the storage device 10 as the link information. In some implementations, the storage device 10 may include a Uniform Resource Identifier (URL) identifying a path in the memory of the storage device 10 where the original file is stored. In some instances, the link information may be included in EXIF information, and/or other metadata, that is included in the optimized file.

According to various aspects of the disclosure, the link information may be stored in an image thumbnail form. In such a case, the storage device 10 may provide thumbnail information corresponding to a backup file to the electronic device 100. The electronic device 100 may receive a corresponding backup file using thumbnail information. For example, the backup file may include at least one image.

FIG. 5 is a flowchart of an example of a process according to aspects of the disclosure. According to the process, at operation 500, the electronic device 100 connects to the storage device 10. At operation 510, the electronic device 100 transmits a copy of an original file stored at the electronic device 100 to the storage device 10. At operation 520, the electronic device 100 determines whether the transmission is complete.

When the transmission is complete, at operation 530, the electronic device 100 receives from the storage device 10 an optimized file corresponding to the original file. The optimized file may be an optimized version of the original file. As noted above, the optimized file may be generated by one or more of:

-   -   (1) Changing the encoding scheme used to encode the content of         the original file;     -   (2) Compressing the original file;     -   (3) Changing one or more attributes of the original file that         specify whether the file can be edited.     -   (4) Changing a format of the original file; and     -   (5) Changing a resolution of media content that is stored in the         original file.

In some implementations, the optimized file may be generated by the storage device 10 based on environment information for the electronic device. The environment information may identify any suitable characteristic of the software and/or hardware that is part of the electronic device, such as memory capacity, processor speed, usable memory capacity, transmission speed etc. In some implementations, the environment information may be provided to the storage device 10 by the electronic device 100. In some implementations, generating the optimized file based on the environment information may include setting (or selecting) a characteristic of the optimized file based on a characteristic of the electronic device. For example, a resolution of the optimized file may be set based on the storage capacity of the electronic device 100. If the electronic device 100 has a larger amount of memory space available, the optimized file may be generated to have higher resolution than otherwise. At operation 540, the electronic device 100 replaces the original file with the optimized file. In some implementations, operation 540 may be performed in the same way as operation 440.

FIG. 6 is a flowchart of a process according to aspects of the disclosure. According to the process, at operation 600, the electronic device 100 connects to the storage device 10. At operation 602, the electronic device 100 transmits an original file to the storage device 10. At operation 604, the storage device 10 may store the original file. At operation 606, the storage device 10 transmits a backup completion signal to the electronic device 100. At operation 608, the electronic device 100 requests from the storage device 10 an optimized file corresponding to the original file (e.g., an optimized file that is generated based on the original file). At operation 610, the storage device 10 requests environment information of the electronic device 100 from the electronic device 100. In some implementations, environmental information may be requested when the storage device 10 determines that it has no environment information record for the electronic device 100 stored in its local memory. At operation 612, the electronic device 100 transmits the environment information to the storage device 10.

At operation 614, the storage device 10, generates an optimized file corresponding to the original file. As noted above the optimized file may be an optimized version of the original file. In some implementations, the optimized file may be generated based on environment information of the electronic device 100. At operation 616, the storage device 10 transmits the optimized file to the electronic device 100. At operation 618, the electronic device 100, stores the optimized file as a replacement to the original file.

At operation 620, the electronic device 100 executes the stored optimized file. Executing the optimized file may include displaying and/or otherwise outputting the optimized file. At operation 622, the electronic device 100 requests the original file from the storage device 10. In some implementations, the electronic device 100 may request the original file in response to detecting that a reference gesture is input to the optimized file. At operation 624, the storage device 10 transmits the original file in response to the request.

For example, when the optimized file is an image file, the electronic device 100 may display the image on the touch screen 190. After the image is displayed, as shown in FIGS. 14A and 14B, when a user touches a predetermined area of an optimized image file 1400 with two fingers F and drags the two fingers F from an internal direction to an external direction, a pinch in function in which a predetermined area of the optimized image file 1400 is enlarged may be performed. When a predetermined area of the optimized image file 1400 is enlarged to a reference ratio or more, the electronic device 100 may request the original file from the storage device 10. Thus in some implementations, the electronic device 100 may request the original file from the storage device 10 in response to: (i) receiving a given type input, (ii) receiving input having a predetermined characteristic, (iii) receiving input to displayed (or otherwise output) content of the optimized file while the optimized file is displayed or otherwise input, and/or any combination of i, ii, and iii.

In some implementations, the request may be generated based on link information associated with both the optimized file and the original file. As noted above, in some implementations, the link information may be encoded into the optimized image file 1400 and used to retrieve the original image file 1410 from the storage device 10. Thus, in some implementations, transmitting the request for the original image file 1410 may include extracting the link information from the optimized image file 1400 (or otherwise identifying the link information).

FIG. 7 is a flowchart of a process according to aspects of the disclosure. Referring to FIG. 7, at operation 700, the electronic device 100 connects to the storage device 10 over the network 30. At operation 710, the electronic device 100 transmits an original file to the storage device 10. At operation 720, the storage device 10 stores the original file. At operation 730, the second electronic device 20 connects to the storage device 10. At operation 740, the second electronic device 20 requests the original file from the storage device 10. At operation 750, the storage device 10 transmits to the second electronic device 20 a request for environment information of the second electronic device 20. At operation 760, the second electronic device 20 transmits the environment information to the storage device 10. At operation 770, the storage device 10 generates an optimized file corresponding to the original file. In some implementations, the optimized file may be generated based on the environment information of the second electronic device 20. At operation 780, the storage device 10 transmits the optimized file to the second electronic device 20.

FIG. 8 is a flowchart of a process according to aspects of the disclosure. According to the process, at operation 800, the electronic device 100 connects to the storage device 10 over the network 30. At operation 810, the electronic device 100 receives from the storage device 10 an optimized file corresponding to an original file that was previously stored at the storage device 10. At operation 820, the electronic device 100 executes the received optimized file. At operation 830, the electronic device 100 detects input of a reference gesture to the optimized file. The reference gesture may include at least one action of a pinch-in action, a tab action, a flicking action, a touch and drag action, a tab and hold action, and a multi tab action of an optimized file.

According to aspects of the disclosure, when the optimized file is an image file, the electronic device 100 may display the image on the touch screen 190 and perform an editing function of the image. The image file may include thumbnail image. If the input of a reference gesture to the optimized file is detected in operation 830, at operation 840, the electronic device 100 receives an original file corresponding to the optimized file from the storage device 10. At operation 850, the electronic device 100 executes the received original file.

As shown in FIGS. 14A and 14B, an optimized image file 1400 may be displayed on the electronic device 100. When the user performs a pinch gesture on the optimized file, the optimized image file 1400 may be zoomed in. When the user desires the optimized image file to be zoomed in excess of a reference zoom ratio, the electronic device 100 may request the original file corresponding to the optimized file 1400 from the storage device 10. That is, when the electronic device 100 detects a zoom-in gesture, the electronic device 100 may receive from the storage device 10 an original image file 1410 that corresponds to the optimized image file 1400. Afterwards, the electronic device 100 may display the original image file 1410 in place of the optimized image file 1400. However, the reference gesture is not limited thereto and may include various gesture actions in addition to a pinch-in action.

Thus, as illustrated, in some implementations, the same reference gesture may trigger the performance of multiple operations. More precisely, the same reference gesture may cause two or more of (i) the transmittal of a request for an original file corresponding to a rendered optimized file to be transmitted; (ii) the removal of the optimized file from display; and (iii) the display of the original file in place of the optimized file. As noted above, the reference gesture may be an input attempting to enter text or other content into the optimized file.

As shown in FIG. 15, when the electronic device 100 streams an original video file to another electronic device 1500 using a wireless connection method, for example, a Digital Living Network Alliance (DLNA) or airplay function and executes the video file in the another electronic device 1500, the electronic device 100 may receive an original video 1510 of the video file from the storage device 10. The electronic device 100 may transmit the received original video 1510 to the another electronic device 1500. That is, when the another electronic device 1500 executes an optimized video received from the electronic device 100, if a quality (e.g. resolution) thereof is reduced and displayed, the electronic device 100 may request the original file from the storage device 10. However, it is not limited thereto and a reference gesture may be set by a user.

According to aspects of the disclosure, when an optimized file is a text file, a reference gesture may include detection of a touch pen.

As shown in FIGS. 16A and 16B, in a state in which an optimized read-only text file 1610 is executed (e.g., displayed) when the electronic device 100 detects a touch with a touch pen T (or another input for editing the text file), the electronic device 100 may request an original text file 1610 corresponding to the optimized text file 1600 from the storage device 10. In such a case, the electronic device 100 may replace the optimized text file 1600, which is read-only, with the original text file 1610 that is editable. However, a reference gesture is not limited thereto and a specific key input or predetermined various reference gestures may be used in addition to detection of a touch pen.

It is to be understood that the processes disclosed herein are provided as an example only. At least some of the operations that are part of these processes may be performed in a different order, concurrently, or altogether omitted. Each of the operations discussed with respect to FIGS. 1-16A may be performed by a processor and/or other processing circuitry.
